To all whom it may concern:

Be it known that 1, Answer SOMMER- MEYER, a subject of the King of Prussia, and resident of-65 Gitschinerstrasse, Berlin, in the German Empire, having invented a new and useful Apparatus for the Treatmentof Carr/asses, Slaughter-House Waste, and the Like, of which the following is a specification.

This invention relates to an improved apparatus for the treatment of carcasses, slaughter-house waste and the like and has for its object to obtain meat meal, fat, glue and other constituents therefrom, and the invention relates to the type of apparatus in which the material is subjected to the action of saturated steam under pressure, or to the vapors of non-fatty substances such as benzin, carbon tetrachlorid, carbon-bisulfid or the like, the fat and gelatinous constituents being extracted thereby. The residue which remains and which is more or less freed from fatty and gelatinous constituents, is then dried and results in a residue in the form of a brown powder, the fatty and gelatinous constituents being obtained as by products and separating therefrom, in the form of a liquid. 1

Hitherto it has been usual to carry out the extracting and drying processes in succession in the same apparatus so that it is necessary to complete the treatment of the charge in the apparatus and to discharge the same before a fresh charge may be treated therein. In order to accelerate the process, it has therefore been proposed to carry out the extracting and drying processes in separate apparatus so that the material after being treated with an extracting medium in the one apparatus, may be transferred to the drying apparatus and the extracting apparatus thereupon filled with a new charge. This process however is also too slow for application in pases where large quantities of the material are to be dealt with, as the charge in the extracting apparatus must be fully dried and discharged therefrom before further material may be admitted to the extracting apparatus. These processes necessitatethe erection of large plants where considerable uantities of the Specification of Letters Patent.

therefrom without relieving the pressure in the extracting apparatus.

My invention also comprises means whereby the material under treatment is finely divided in the extracting apparatus by subjecting the same to an agitatory or rotary movement, the material in this finely divided state being then drawn ofi' from the extracting apparatus.

By this means it is possible to treat large quantities of the material in the same apparatus, the treatment being carried out continuously and fresh material being fed thereto as the process proceeds.

In order that the invention may be more clearly understood reference is made to the accompanying drawing wherein is shown by way of example the preferred construction of up exams for carrying out the invention.

Re erring to the drawing: the extracting apparatus comprises a horizontal Vessel A within which is rotatably mounted a: cylindrical or conically formed perforated drum B, the latter being driven by means of suitable gearing F from a counter shaft. Opening into the end of the drum B is a feedconduit C by way of which the material is fed to the interior of the drum B, said con duit C being of comparatively large div ameter. The vessel A is provided at its lower end with an outlet D which is also of comparatively large diameter, said outlet D communicating with the drying apparatus or other vessel in which the material vided material as well 'as'the liquid constituents to the outlet D.

- tionsin the drum B after which'it is dispose a feeding receptacle G is connected to the conduit 0, communication between the receptacle-G and conduit C being capable of regulation by means of a slide valve H.

The receptacle G is also provided with 'a pipe 'M opening into the atmosphere and which may be controlled by means of a valve N l {The method of carrying out the process is as follows: The drum B. isfilled by opening the valve H and supplying material by way of the cover G. When the drum B has been'filled to the desired extent the valve H is closed and'the extracting process carried out by admitting a suitable extracting medium by way of the valved pipe'O. The constituents of the material in the drum'B are thus extracted'and after a certain length of time, a further charge may be supplied to the drum B. For this purpose the receptacle G is filled anew with the material and the cover G tightly closed, whereuponthe valve L is opened and the pressure in the vessel A and receptacle G thus equalized, so
